Upton Tractor

Recommended Posts

this got rescued , yesterday

 

Upton tractor

upton had this theory that a 2wd tractor should be able to outpull a 4wd tractor

 

so he set about building them

 

this is an early one

originally powered by Nissan UD4 and used M3 grant drivetrain

the grant axle developed problems, so the grant drivetrain came out and 2 x 5speed gearboxes fitted,along with a mack diff     original UD4 had been taken out and a AEC/Leyland V8 engine fitted

Those nissan UD engines are a great reliable engine.  Does the V8 turn over?  Going to fix it up?

That name sounded familiar.  There is no way in **** that tractor would out pull any 4x4 the way its setup.  Found this article in my Farm Show magazine.  There are a couple other articles on guys building their own big 2 wheel drive tractors and claiming they are just as good or better then a 4 wheel drive.  Two things.  Upton and these other guys don't know what hills are and don't know the meaning of "efficiency."  A 350 hp tractor weighing 51,000 lbs??

I tend to agree with you

or what happens when a heavily weighted and loaded 2wd tractor does in soft soil

same thing seems to be happening with large FWA tractors,             equal size 4wd , still outperforms  them
